Posted this in the other thread, but to me it comes down to what Mel Tucker's ultimate goal is. I suspect he wants to be an NFL head coach. If that's true, I'm not sure how jumping to LSU makes sense. I would think he sticks around MSU for another two years, and then goes to the NFL.
If he wants to be at the best possible college to try and win a national title at, then I could see him going to Baton Rouge, and wouldn't blame him. For some reason I don't see him going to USC, just more of a gut feel than anything.
